Abstract
Mixed crystals of potassium‒cobalt sulfate hexahydrate/potassium‒nickel sulfate hexahydrate (K2Co(SO4)2 · 6H2O/K2Ni(SO4)2 · 6H2O (KCNSH)) have been grown from a solution with an isomorphic-component ratio of KCSH : KNSH = 1 : 2. The presence of mosaic microheterogeneity in KCNSH crystals at a level of ∼2 at % is confirmed, and its dependence on supercooling is studied. The radial heterogeneity of KCNSH crystals is investigated as a function of the growth direction and rate. The heterogeneity of Co concentration in different samples is shown to vary from 0.2 to 0.8 wt %.
